Description

I will review some key aspects of the physics of neutron star superfluidity and superconductivity, which play an important role in the phenomena of pulsar timing noise and rotational glitches. New results will be presented from quantum mechanical Gross-Pitaevskii simulations of vortex avalanches in a pinned, decelerating superfluid, which show the correlated nature of vortex motion during glitches explicitly for the first time and provide a robust explanation of certain aspects of glitch statistics. Future gravitational wave experiments probing neutron star superfluidity and superconductivity will be evaluated critically and related to fundamental open questions concerning the physics of bulk nuclear matter.
